摘要
研究了遮荫和干旱胁迫对银杏枝叶种群生长的影响,结果表明,遮荫可增加叶面积,延长其生长期,促进长枝1和2及株高的增长,但对短枝数量无明显影响;重度干旱抑制了长枝1和2及株高的生长,中度干旱对长枝1作用不明显,但促进了长枝2的生长,干旱胁迫对短枝数量无明显影响.
The effect of environmental stress on modular growth of leaf and branch population in Ginkgo biloba was investigated with different shading and drought treatments. The results indicated that shading increased the leaf area and prolonged the growth period of leaf,growth of long branch 1 and 2,and the height were greatly improved by shading but it had little influence on the number of short branch. Severe drought inhabited the growth of long branch 1 and 2,and the height,while mild drought had little influence on the growth of long branch 1 but promoted the growth of long branch 2. Drought had little influence on the number of short branch.
